Mu dziko la kupanga thovu la polyurethane, ma catalyst amagwira ntchito yofunika kwambiri podziwa makhalidwe ndi ubwino wa chinthu chomaliza. Chimodzi mwa zinthuzi ndi BDMAEE (Bis(dimethylaminoethyl) ether), amine yogwira ntchito kwambiri ya tertiary yomwe imadziwika chifukwa cha mphamvu yake yayikulu pakupanga thovu mu...
Ma catalyst a polyurethane amagwira ntchito yofunika kwambiri pakukonza magwiridwe antchito ndi magwiridwe antchito a zinthu za polyurethane. Pakati pa ma catalyst ambiri omwe alipo, MXC-t125 imadziwika kuti ndi catalyst yachitsulo yopanda lead yomwe imadziwika ndi mawonekedwe ake apadera komanso kugwiritsa ntchito kwake mosiyanasiyana. Nkhaniyi ikufotokoza za...
Ma catalyst a polyurethane amagwira ntchito yofunika kwambiri popanga ma polyurethane, omwe ndi mphamvu yoyendetsera zochita za mankhwala zomwe zimapanga zinthu zosiyanasiyanazi. Pakati pa ma catalyst osiyanasiyana omwe alipo, MXC-T120 ndi njira yamphamvu komanso yothandiza kwambiri pa mitundu yosiyanasiyana ya zinthu...
Ma catalyst a polyurethane, monga MXS-6 (DC-193), ndi ofunikira kwambiri popanga ma soli a polyurethane (PU), omwe ndi maziko a makampani opanga nsapato. Ma catalyst awa, kuphatikizapo ma silicone surfactants omwe amagwiritsidwa ntchito kwambiri m'makampani, ndi ofunikira popanga thovu lolimba la polyurethane,...
Ma catalyst a polyurethane, monga MXC-T, amagwira ntchito yofunika kwambiri popanga mitundu yosiyanasiyana ya ma thovu a polyurethane, kuphatikizapo ma thovu ofewa a polyether, ma thovu opangidwa, ma thovu olimba pang'ono, ndi ma thovu olimba. Pakati pa izi, thovu lofewa la polyurethane limadziwika chifukwa chogwiritsidwa ntchito kwambiri m'mafakitale ambiri...
Ma thovu a polyurethane amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana chifukwa cha mphamvu zawo zabwino zotetezera kutentha komanso kulimba kwa kapangidwe kake. Mtundu umodzi wofunikira wa thovu la polyurethane ndi thovu lotsekedwa, lodziwika chifukwa cha kulimba kwake komanso kulimba kwake. Monga ogulitsa ma catalyst a polyurethane, timazindikira kufunika kopanda...
Ma panel a masangweji amagwiritsidwa ntchito kwambiri pomanga chifukwa cha mphamvu zawo zabwino zotetezera kutentha, kulimba kwa kapangidwe kake, komanso kusavuta kuyika. Zinthu zofunika kwambiri pa mapanelo awa zitha kupangidwa kuchokera ku thovu zosiyanasiyana, monga thovu la polyurethane, bolodi la polystyrene bead, kapena galasi la thovu. Pakati pa izi, pol...
Ma catalyst a polyurethane amagwira ntchito yofunika kwambiri popanga ma thovu a polyurethane, ma elastomer, zokutira, zomatira, ndi zomatira. Pakati pa ma catalyst awa, T-125 ndi chisankho chodziwika bwino, makamaka popanga ma thovu olimba a polyurethane. Nkhaniyi ikufotokoza za makhalidwe a T-1...
Ma catalyst a polyurethane amagwira ntchito yofunika kwambiri popanga zinthu za polyurethane pokhudza kuchuluka kwa zomwe zimachitika komanso mawonekedwe omaliza a zinthuzo. Pakati pa ma catalyst osiyanasiyana omwe alipo, MXC-T120 imadziwika bwino chifukwa cha ntchito yake yabwino kwambiri popanga thovu lolimba la polyurethane, lomwe...
